Clear Schematic for 41-255
#16

RossH -

Were you looking at our copy of the 1941 Yearbook, or one that you found elsewhere?

What's really funny is I looked at the pages and saw 255 and it took me 30 sec of looking at the schematic trying to figure out why it wasn't matching what I had before it dawned on me - I had transposed the numbers in my head.

This is perfect. Besides starting to work on one of these I am going to recreate this schematic from scratch. I've done a few ten others but this will be my first Philco recreation. I'll post when it's completed and gone over a few times. 

Thank you very much for your time and consideration in doing this, and a big thank you to all who chimed in.

Hi Ross,
I don't know if you still need a clear schematic for the 41-255 but here is one that I cleaned up. I added pin numbers on the tubes and corrected 2 part #s (#29 and 33 were reversed on the schematic). Also, voltages are in dark red, and where provided, I color-coded the wire color name.

AH Just noticed 1 error on my cleaned-up schematic...
Part # 27 - the 8uf electrolytic cap...The lead that is marked RED should read GRN (green). Old eyes are not what they used to be!
